What is Vue DnD Kit?

Vue DnD Kit is a comprehensive ecosystem of drag and drop libraries for Vue 3 applications. It provides a set of modular, high-performance tools to build complex drag and drop interfaces with minimal effort.

Philosophy

Vue DnD Kit was built with several core principles in mind:

• Modularity: Use only what you need, keeping your bundle size minimal
• Performance: Optimized for smooth interactions, even with large lists
• Accessibility: Built with ARIA support and keyboard navigation
• Developer Experience: Intuitive APIs and comprehensive TypeScript support
• Flexibility: Adaptable to a wide range of use cases without being opinionated

The Problem

Building drag and drop interfaces from scratch is challenging. You need to handle:

• Touch and mouse events across different devices
• Accessibility requirements for all users
• Performance optimization for smooth interactions
• Complex state management during drag operations
• Cross-browser compatibility issues
• Collision detection between elements
• Animation and transitions for visual feedback

Most existing solutions are either too simple for complex use cases or too opinionated, limiting your design freedom.

The Solution

Vue DnD Kit solves these problems with a thoughtful, composable approach that gives you powerful building blocks while maintaining flexibility in how you use them.

Ecosystem Overview

Vue DnD Kit is divided into several packages to keep your bundle size minimal:

@vue-dnd-kit/core

The foundation package providing essential drag and drop functionality through composables like useDraggable and useDroppable.

@vue-dnd-kit/components

Ready-to-use components for common drag and drop patterns such as sortable lists, drag overlays, and more.

@vue-dnd-kit/utils

Utility functions for collision detection, geometry calculations, auto-scrolling, and other helpful tools.

@vue-dnd-kit/devtools

Development tools to debug and visualize your drag and drop interfaces during development.

Key Concepts

Vue DnD Kit revolves around a few core concepts:

• Draggable: Elements that can be picked up and moved
• Droppable: Zones where draggable elements can be placed
• Sensors: Detect and normalize user interactions (mouse, touch, keyboard)
• Collision Detection: Determine when and where elements intersect
• DnD Store: Manage the state of drag operations across components

These concepts work together to create a cohesive system that's both powerful and flexible.

API Level Explained

Vue DnD Kit offers a unique hybrid approach to its API:

• High-level API: Ready-to-use components and composables for quick implementation
• Low-level API: Utility classes and functions for custom implementations and advanced use cases
• Mixed approach: Ability to use both high and low-level APIs together for maximum flexibility

This hybrid approach means you can start with high-level components for rapid development, then gradually customize with low-level utilities as your needs evolve.

Use Cases

Vue DnD Kit is suitable for a wide range of applications:

• Sortable Lists: Reorder items within a list
• Kanban Boards: Move items between columns
• File Uploads: Drag and drop files from the desktop
• Page Builders: Create layouts by dragging components
• Form Builders: Design forms by arranging form elements
• Data Tables: Reorder rows or columns
• Tree Views: Reorganize hierarchical data
• Shopping Carts: Drag products to a cart
